Arrowproofing costs around +4-6 gold per clothing item, depending on the size; it doesn't protect areas the clothing doesn't cover.  She could get full merchant's robes with long sleeves arrowproofed for +6 gold, and that would cover most of her, but that wouldn't look fashionable or rich on a student Bella's age.  Separate pants and skirt will cost +5 gold each.  The cost of the enchantment on a clothing item is not linear in its surface area.
